Your ShipStation rules might work 60-70% of the time, but when they're wrong, it costs you money. Your team doesn't have time to check every order and find the best rate manually. That's where String comes in! String knows your products, package sizes, and carrier options. When a new order comes in, we automatically pick the best option in real time. Instead of being right only 70% of the time, you now get the best rate 100% of the time—saving you money on every shipment!
No! String is built to get your orders to customers fast while also saving you money. String checks delivery times for every shipment. If a shipping option won't arrive on time, String filters it out automatically. This means you get the best rate without slowing down delivery—and sometimes, even faster shipping!
String finds the smallest and best box for every order. We keep track of all your products' sizes and weights and test different ways to fit them into the smallest box possible. If a product needs special packing, no problem! String follows your rules to make sure everything is packed just right. Need to add new products or packages? It's easy! No matter how many items you have, String will always find the best fit to save you money.
No! String integrates seamlessly with ShipStation—no changes needed, just savings.
